I have a confession: I’ve seen the movie but I forgot most of it…curses! why do I spend so much money on movies when I forget one week later. 
Anyway back to your reel.
Before you touch on stuff like animation or technical stuff, You have to work on your camera direction, composition and staging. Which I think will benefit you as a design student.
Pay attention to the camera axis line, rule of thirds and keeping your subject in frame. Most of these mistakes can be eliminated when story boarding and creating an animatic or leica reel.

Camera axis
the path of action of the dragon must be clear, if its flying from screen left to right in one shot, don’t reverse his direction in the next shot. Likewise with eye direction. Also, if your dragon is on the left half of the screen in one shot don’t throw him to the right side in the next shot.

Something I call: Progressing the action.
Tracking a moving object is tricky, and this is the part that is hard to explain. Don’t “over shoot” the camera or it will seem like the dragon is loosing speed and regressing from the frame. When the dragon is flying from screen left to right, start it out at the left side and progress it forward to the centre of the frame. this way, not only is the dragon moving forward in the environment, its moving forward within the screen too.
Sorry of the WOT. Have fun Animating!
